Hi all I'm 52. I too was diagnosed with smouldering mm in 2009 after routine blood test. It just so happens that at that time I had a blood clot in my leg that travelled to my lungs.Had a hysterectomy too that same year. I feel a bit of a fraud with smm as i go for blood tests every 4 months but thank Gd apart from the blood clot and hysterectomy (oh and blood transfusion) 4 years ago, I feel very well.
